While camping this weekend in southern Missouri, I saw two worms come out of a spider. By looking at pictures on the Internet, I would characterize the worms as roundworms because they were long-probably several inches each-and round. After the worms came out, the spider looked like it was having a seizure and it did not move much after that. Being a science teacher, I was entranced in the whole process as it was happening before me. Can you tell me more information about these worms that infect spiders?

I am sorry for the late and inadequate reply, but here is what I know: most roundworms (nematodes) are free living in the soil or associated with soil organisms. I haven't found anything regarding parasites in spiders, but there are a number of possibilities, most organisms are sometimes host for internal parasitic worms.

The following site gives information about small worms that have been found in spiders.

Thanks to Charlie R. for this addition.
